With Maya Bay no longer an option as of 2018, travellers can still enjoy the warm blue-green Andaman Sea, the blinding white sands, and marvelous limestone when visiting the Similan Islands. The islands offer a quiet scene, combining rainforests and pristine beaches with a touch of history, having been made a UNESCO World Heritage site in 1982. Intrepid Travel's Cruising the Thai Islands adventure cruise is specifically curated to take travellers to the country's less-visited islands without tourists.
